Bug description:
  [Environment]

  Stein OpenStack
  Ubuntu Bionic

  [Description]

  From my understanding the current Octavia API should be backwards
  compatible with LBaaS v2, therefore, the current LBaaS v2 pollster [1]
  should suffice to gather the following meters:

  meters:

  - network.services.lb.outgoing.bytes
  - network.services.lb.incoming.bytes
  - network.services.lb.pool
  - network.services.lb.listener
  - network.services.lb.member
  - network.services.lb.health_monitor
  - network.services.lb.loadbalancer
  - network.services.lb.total.connections
  - network.services.lb.active.connections

  However, the following warning is noticed when restarted the
  ceilometer services.

  2999:2019-11-07 15:05:41.665 22487 WARNING ceilometer.publisher.gnocchi [-] metric network.services.lb.loadbalancer is not handled by Gnocchi
  3467:2019-11-07 15:06:21.830 3916 WARNING ceilometer.publisher.gnocchi [-] metric network.services.lb.loadbalancer is not handled by Gnocchi

  In fact, by checking at the gnocchi metric list (https://pastebin.canonical.com/p/zyMTFv8vww/) the network.services.lb
  metrics/resources haven't been created.

  The reason is that for a gnocchi resource to exist, ceilometer has to create the resource type explicitly.
  This action is commanded by the ceilometer gnocchi client [2] and it uses the file /usr/lib/python3/dist-packages/ceilometer/publisher/data/gnocchi_resources.yaml
  for the resource definitions, which doesn't includes the lbaasv2 directives.

  [Test case]

  1) Deploy a gnocchi backed ceilometer unit with octavia deployed.
  2) check that lb meters aren't being gathered

  $ gnocchi metric list|grep loadbalancer | wc -l
  0
  3) install the patched version
  4) configure all pollsters
  $  juju config ceilometer enable-all-pollsters=true
  5) sudo systemctl restart ceilometer*
  6) sudo ceilometer-upgrade
  7) Check that lb metrics are being gathered

  [Regression Potential]

  There is no regression potential identified on this patch as it uses
  the new metrics upgrade path and it doesn't
  enables any new metrics if the lbaasv2 pollster isn't configured.

  [Proposed solution]

  Enable the resources on /usr/lib/python3/dist packages/ceilometer/publisher/data/gnocchi_resources.yaml
  and modify the gnocchi client provider. I am able to gather the metrics for the octavia load balancers.
